、大重量になる。Therefore, an axial force is continuously applied to the housing during the cutting operation. As a result, uneven loads are applied to the housing. Furthermore, due to such an axial force, the holder must be supported within the housing via roller bearings. Therefore, the housing becomes large and heavy.

The tool holder 11 includes an arbor 24 and an adapter 25. The arbor 24 is connected to the main shaft of the machine by a clamp bolt (not shown). Generally, the clamp bolts are screwed into the rear portions of holes 26 that extend through the arbor 24. The front part of hole 26 receives a clamp bolt 27. The adapter 25 is fastened to the arbor 24 by the clamp bolt 27 . The short Okawa drill 12 is attached to the tool holder 11 in a known manner. The short drill 12 is equipped with two indexable cutting inserts 13, 14 made of cemented carbide. These cutting insert pieces 13.
14 overlap in the radial direction. The drill 12 is adapted to drill short holes in metal bodies, preferably with a depth up to twice the diameter of the hole.

タ２５内の凹所３３の底部表面に押し付けられている。Within the housing 20, an angular locking member 28 is mounted for pivoting about an axis 29. This locking member 28 has an arm portion 30 extending in the radial direction. A contact portion 31 is provided on the outer portion of the locking member 28 . This contact 31 is pressed by a spring 32 against the bottom surface of a recess 33 in the adapter 25.

これにより、アダプタ２５及びハウジング２０が確実に
非回転状態で相互連結される。This ensures that the adapter 25 and the housing 20 are interconnected in a non-rotating state.

方に離れる。Initially, the inventive device is equipped for application in machine tools with automatic tool changers. In this case, the housing 20 must be kept in place relative to the coupling member 19 during transport of the tool holder 11. Therefore, a locking action provided by locking member 28 is required. After the tool holder 11 has been mounted on the machine spindle, the nipple 18 is pushed into the coupling member 19. Lock member 2
8 is provided with an arm portion 3 extending in the axial direction. The outer portion 35 of the locking member 28 slides against the outer surface of the coupling member 19 when the nipple 18 is pushed into the coupling member 19. As a result, the locking member 28
9 by a limited angle counterclockwise, the contact part 31 leaves the recess 33. Therefore, housing 2
The tool holder 11 is released from 0. That is, the locking member 28 will not be able to handle the outer portion 3 of the locking member 28 when a radially inwardly directed force is applied to the locking member.
5, the tool holder 11 is attached to the housing 20.
The outer portion 35 of the locking member 28 is then released radially inwardly from the nipple 18.

とアダプタ２５の外側表面とによって提供される。Since no axial acting force remains on the swivel 10 when the tool holder 11 is attached to the machine main shaft, no uneven load is applied to the housing 20. This means that the adapter 25 can be journaled in the housing 20 via a friction bearing. In other words, the swivel is smaller and lighter than in configurations where roller hair rings are required. Two cooperating support surfaces of the friction bearing are provided by the inner surface of the bushes 36 provided within the housing 20 and the outer surface of the adapter 25.
